1 Claim.

This invention relates to an air conditioned canopy and has for itsprincipal object the provision of a small housing to be placed over abed to agreeably comfort an occupant lying therein regardless of thetemperature in the room in which the bed is placed.

A further object of this invention is to provide a canopy adaptable toprivate homes, hotels, and hospitals, the interior of said canopy to beair conditioned to a desired degree of temperature to meet the conditionof an occupant lying in the bed whether normally in good health or apatient to be treated to combat an abnormal condition either by a highor low degree of temperature as the case may require.

A further object of this invention is to construct a light durable framehaving means to detachably secure the same to a bed frame and the saidfirst frame being enclosed with a material that will maintain thetemperature created within, and furthermore the said enclosure being ofsuch material that will avoid condensation when the interior of thecanopy is air conditioned to a low degree of temperature.

A still further object of this invention is to provide accessible meansto a patient from either side of the bed and the said means being aconvenience to enter the canopy and emerge therefrom.

These and other objects will hereinafter be more fully explained,reference being had to the accompanying drawings forming a part thereof,and in which like characters will apply to like parts in the differentviews.

Referring to the drawings:

Fig. 1 is a side elevation of the canopymounted on a bed structure, thecurtain at the head of the canopy being vertically positioned, butadapted to enclose the head of a patient as shown by dotted lines.

Fig. 2 is a foot end view of Fig.

Fig. 3 is a head end view of Fig. 1.

Fig. 4 is a, longitudinal section through the canopy to illustrate theside frame and its jointed sections and direction of their rockingmovements, also the clamping means for the frame to a side rail of abed.

Fig. 5 is a fragmentary plan view of the top of Fig. 4.

Fig. 6 is a fragmentary sectional view taken on line 6-6 in Fig. 1.

Fig. 7 is an enlarged longitudinal section through a standard toillustrate a snap fastener for the textile covering to the frame.

Referring to the drawings in detail, it will be seen that the inventionrelates to a canopy comprising a. pair of standards I and 2 respectivelyfor each side of the structure in spaced relation and removablyconnected to a bed frame as later described, the standards at theirupper ends being hingedly connected to side rods 3 as at A and B and thesaid side rods being rule-jointed as at C and D to fold as indicated byarrows in Fig. 4. Said standards are adapted to rock inward toward eachother at the time of folding the canopy, the side rods 30 beingconnected by cross rods 4 at each end and intermediate thereof.Threadedly engaging on the lower ends of each pair of standards areclamps 5, the jaws of which are adapted to straddle the side rails 6 ofa bed structure and being secured by bolts 1. It will now be seen thatstandards I will function as an anchor while standards 2 are the fulcrumpoints to support the forward extension of the side rods to maintain alevel alignment of the top of the canopy. The frame thus described hasan enclosure 8 preferably made of canvas and being secured to the frameby removable fasteners 9, the sides and foot end portions being adaptedto lap over the bedding to exelude external temperature from theinterior of the canopy, and the head thereof has a curtain ill to closethe same, said curtain being detachably carried by its. respective crossrod and normally vertically positioned, however, the said curtain beingof suitable length to enclose the head of an occupant as shown by dottedlines E; otherwise the head may be exposed by moving the lower extremityof the curtain rearward, but at all times maintain a sealed enclosure.-

As a means to air condition the interior of the canopy, there isprovided a duct I I as a conductor for air injection to the interiorthereof, said duct arranged to communicate through the foot or rear wallof the enclosure concentric thereto or may be otherwise located. Theduct is made likewise of canvas and has suitable annular ribs tomaintain the same tubular in form; furthermore there is provided aflange F for the mouth of the duct and being removably secured by balland socket fasteners I2, the other end being in connection with astandard make of generator as at l3 that may be placed under the bed orelsewhere, or may be connected to an air conditioning plant installed inthe building;

however, it will be understood that the said canopy may be separatelyair conditioned to vary its inward temperature from that in the room inwhich it is placed.

While I have shown the frame constructed of tubular elements, the samemay be varied by the adoption of solid bars, but in any variation themetal is preferably of aluminum alloy, and likewise, the enclosure beingspecified as canvas, the same may be substituted by rubberized fabric orother material so long as the interior or the canopy is substantiallyair tight or at least void 01 free external communication, whereby aneven temperature is maintained for the purpose specified, and such othermodifications may be employed asjlie;witl' in the scope qf the ap- -E;

pended claim.

Having fully described my invention what I claim as new and desire tosecure Letters" ru e-m n ed a 1 t rod for each side of the canopytop,""a pairo'f Patent is:
